Father Malachi Martin had first made reference to a satanic ritual held in Rome in his 1990 non-fiction best-seller about geopolitics and the Vatican, The Keys of This Blood, in which he wrote:

Most frighteningly for [Pope] John Paul [II], he had come up against the irremovable presence of a malign strength in his own Vatican and in certain bishops’ chanceries. It was what knowledgeable Churchmen called the ‘superforce.’ Rumors, always difficult to verify, tied its installation to the beginning of Pope Paul VI’s reign in 1963. Indeed Paul had alluded somberly to ‘the smoke of Satan which has entered the Sanctuary’. . . an oblique reference to an enthronement ceremony by Satanists in the Vatican. Besides, the incidence of Satanic pedophilia—rites and practices— was already documented among certain bishops and priests as widely dispersed as Turin, in Italy, and South Carolina, in the United States. The cultic acts of Satanic pedophilia are considered by professionals to be the culmination of the Fallen Archangel’s rites." (p. 632)

In "Windswept House: A Vatican Novel" Malachi vividly described a ceremony called “The Enthronement of the Fallen Archangel Lucifer” supposedly held in St. Paul’s Chapel in the Vatican, but linked with concurrent satanic rites in the U.S. In the novel, before he dies, a pope leaves a secret account of the situation on his desk for the next occupant of the throne of Peter, a thinly-disguised John Paul II. Martin confirmed that the ceremony did indeed occur as he had described. “Oh yes, it is true; very much so. But the only way I could put that down into print is in novelistic form.”

Martin's accusation of a satanic ritual at the Vatican was also confirmed by John Loeffler, host of the Steel on Steel radio show.  Mr. Loeffler personally asked Fr. Malachi Martin (who had been a regular guest on his show) about the reported dedication to satan within the Vatican: 

You know Malachi confirmed the dedication of the Vatican to satan in a secret ceremony that occurred unknown even to the Pope at that time, that he managed to pick up. And I did ask him, 'Was this true? Did it happen?' And he [Fr. Martin] said, 'yes, it did.'" - John Loeffler (July 29, 2000 radio show)
